To all whom it may concern:

Be it known that I, LOUIS A. Son'onz', a citizen of the United States, residing at Roanoke in the county of Roanoke and State of Virginia, have invented certain new and useful Improvements in Fruit-Jars, of which the following is a specification.

My invention relates to an improvement in fruit-jars, the object being to provide an air-tight and sanitary seal which will insure the preservation of the contents of the jar.

\Vith this object in view, my invention consists in a fruit-jar having a groove formed at the top adapted to receive paraflin or like material, and a lid having a rmg or flange adapted to enter this groove and to be held away from the bottom thereof, so that a film of parafiin shall intervene between the groove and ring or flange at all times, besides occupying the spacebetween the upper edge of the groove and the ring or flange, which latter is of sufficient size to accommodate the surplus paraffin, thus insuring an air-tight joint.

In the accompanying 1 is a vertical section; plan View of the lid; and

drawings :-Figure Fig. 2 is a bottom Fig. 3 is a view of a prepared parafiin ring adapted to fit the mouth of the jar.

The jar 1 is of any approved construction, as for instance the Mason type of fruit-jar, made of glass of any size and shape, except that the glass at the mouth instead of being screw-threaded is enlarged and widened and provided with an annular groove 9-. The outer edge of the mouth is preferably rounded as at 3, and in a slightly higher plane than the inner edge 4.

The lid 6 is made of solid glass and pro-- vided with a ring or flange 6 rounded and enlarged at its lower or outer edge 7 to corthe groove. enlarged edge extends inward, whereby to form a space 8 between it and the inner edge 4 of the mouth to receive the surplus paraffin. This flange or ring is provided with transverse notches 9, 9, for the escape of air. A prepared ring of paraflin 10 is inserted in the groove. The heat from the jar in canning melts the parafiin, the lid is then placed on with the flange or ring in the groove, and the outer edge resting upon the rounded edge 3 of the mouth, thus hold- This mg the ring or flange slightly-away from the bottom of the groove, as shown in Fig. 1, and the lid from the inner edge 4 ofthe mouth. The purpose of this is to provide the space for a film of the paraffin or wax to completely surround the flange or ring, and any surplus to find and fill the space 8 be tween the inner edge 4 of the mouth and the flange or ring; By leaving this space at least one-sixteenth inch (1/16 for the paraifin, 1t not only makes an air-tight joint, but also aflords space for contraction and expansion.

When the lid is on, it is held by any of the well-known forms of wire or tin clamps to hold the lid in place and prevent its being disturbed during handling. After fillin and securing the lid in place, the jar is a lowed to cool, and, as the material contracts,

an absolutely air-tight joint is formed.

By this form of fruit-j ar, I have provided a much more sanitary and hygienic jar than heretofore, which at the same time eliminates the most important objections to the extent than the groove for forming a continuous channel beneath the ring, and said ring of such a diameter that when fitted to the groove a greater channel is left on the inside of the ring than on the outside, an enlargement provided on the lower inner edge of the ring, and said lip adapted, when in place, to rest on the outer rim of the jar so that as a sealing medium is placed in the groove and the lid is fitted to the jar, the sealing medium will close up around the ring and over the enlarged portion.

In testimony whereof I afiix my signature,

.in the presence of two witnesses.
